Definitely horror movies, but there is definitely a huge gap in quality for films within the genre. Also, it can be further dissected into so many categories. I prefer a horror movie that is more psychological and not easily predictable. I am not really into slasher films unless the plot is at least unique. For me a horror film is one that is dark and has content that makes people cringe in thought. A movie like American Psycho would be a great example because you find yourself awkwardly rooting for the villain.
